ROPE-SOCKET.

Application filed March 17, 1916.

To all whom it may concern:

Be it known that we, FRANK TV. SHIREY and JOHN W. Donn, citizens of theUnited States, residing at Tulsa, in the county of Tulsa and State ofOklahoma, have invented new and useful Improvements in Rope- Sockets, ofwhich the following is a specification.

This invention relates to rope sockets, and it is an improvement on thedevice of this class for which Letters Patent of the United States, No.1,061,134, were granted to us on May 6, 1913..

The present invention has among its objects to simplify and improve thegeneral construction; to lessen the cost of manufacture; to provide forthe easy and convenient assembling and disassembling of parts; and toenable a heavier spring to be used than is possible by the constructionnow usually employed.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same con sists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawing,--

Figure 1 is a side elevation of a rope socket constructed in accordancewith the invention.

Fig. 2 is a sectional view taken on the line 22 in Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 33 in Fig. 2.

Fig. 4 is a transverse sectional view taken on the line 41 in Fig. 2.

Fig. 5 is a vertical sectional View of the mandrel or plunger detached.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The body 15 of the improved rope socket is provided at its upper endwith an externally threaded neck 16 and at its lower end with a taperedinternally threaded socket 16 which is adapted to receive thecorrespondingly threaded extremity of a drill tool or 'pering bore ofthe mandrel.

a reducing sub or the like. The body 15 has a longitudinal boreextending through the entire length thereof, the upper end portion ofsaid bore being of relatively small diameter, as indicated. at 17, whilethe lower end portion which extends through the greater portion of thebody is of relatively large diameter, as seen at 18. The enlargedportion 18 of the bore"communicates with the threaded socket 16. Thewalls of the socket are provided at diametrically opposite sides withvertical slots 19 which communicate at their inner ends with theenlarged portion of the bore at the lower end of said enlarged portionbut above the threaded socket portion.

A cylindrical mandrel or plunger 20 is fitted to slide in the enlargedportion 18 of the bore, said mandrel having a short neck 21 at the upperend thereof. The said mandrel is formed with a tapered bore 22 extending longitudinally therethrough, said bore being intercepted nearits lower end by i a transverse slot 23 which is adapted to registerwith the slots 19 in the opposite sides of the body portion 15. Themandrel 20 receives the lower end portion of the rope or cable 2 1 whichis babbitted or otherwise fixed in any well known manner in the ta- Themandrel is connected with the body member 15 by a key 25 which extendstransversely through the slot 23 of the mandrel the end portions of saidkey being disposed within the slots 19, the cable being therebyprevented from twisting or turning with respect to the socket memberwhile the socket member carrying the tool is free to move longitudinallywith respect to the mandrel and the cable. A strong coiled spring 26 isplaced in the enlarged portion 18 of the bore within the socket member,said spring abutting at its lower end on the mandrel and at its upperend on the shoulder 27 formed at the junc ture of the large and smallportions of the bore. The body portion 15 of the socket member isprovided near its lower end with flattened portions or recesses 28, saidfiattened portions serving to form a convenient seat for a wrench orother tool by means of which the socket member may be held againstrotation while the tool, which is not shown, is connected with thethreaded socket provided for its reception at the lower end of the body.

In our former patent, hereinbefore refruitful source of annoyance.

ferred to, the mandrel or plunger is provided with a reduced portion orneck of considerable length, the same extendingthe socket member intoslots extending entirely through the side Walls of said socket member,the construction is simplified and cheapened, and the work of assemblingor disassembling the parts Will be much reduced. I It may be stated thatby practical experimentation the improved device herein described hasbeen found to be thoroughly useful and eflicient for the purposes forWhich it is provided.

When the improved rope-socket is used in starting a Well it is preferredto remove the key '25, thus Permitting the cable to rotate to keep theline from kinking in running Copiei 0! this patent may be obtained forfive cents each, by addressing the Commissioner of Patents,

oft slack in the rope. The key may be subsequently restored to itsposition as herein described. I

Having; thus described the invention, What is claimed as neW,'is: v

In a device of the class described, a cylindrical body member having abore, the upper end of which is reduced to form a shoulder or offset,said body member having slots extending through the side Walls thereof,a mandrel operating in the large portion of the bore, a cable extendingthrough the reduced portion of the bore and connected s'ecurely/With themandrel, a removable key extending through the mandrel into the slots inthe Walls of the body member, and a spring coiled about the cable andabutting at one end on the mandrel and at the other FRANK W. snrnnr.JOHN W.
